Donkey Kong's trusty partner Diddy Kong uses his light weight and agility to get around quickly! For his Final Smash, Diddy takes to the air with his Rocketbarrel while firing his popguns. The final hit is seriously powerful!

Diddy Kong (ディディーコング, Diddy Kong) is a playable character in Super Smash Bros. Ultimate. He was officially confirmed on June 12th, 2018 alongside Olimar and the rest of the returning roster. Unlike his previous appearances in the Super Smash Bros. series, Diddy Kong is now an unlockable character instead of a starter character. Diddy Kong is classified as fighter #36.

Diddy Kong once again retains his realistic chimpanzee screeches that were used in both Brawl and Smash 4.

Having been one of the most notorious top tier fighters in early Super Smash Bros. 4 and remaining a dominant top-tier character throughout the game's lifespan, Diddy Kong was noticeably nerfed in the transition to Ultimate. His staple moves have all been worsened in various ways, hindering his once excellent neutral game; the most notable example is his Banana Peel, which cannot be grabbed as quickly due to him releasing it at a higher arc, and although it can now be thrown twice at opponents before disappearing, this also gives them more opportunities to use it against him. Among other examples, Monkey Flip has more ending lag and gives less distance, up aerial is harder to hit due to possessing a large blind spot in front of Diddy, and his up tilt and down tilt, the latter having been previously infamous for easily setting up combos and KO setups into his up smash, have shorter range that makes them harder to take advantage of. Additionally, Rocketbarrel Boost travels a drastically shorter distance when fully charged, and the charge time itself was reduced by a third, to the point that the difference in distance between the uncharged and fully charged version is now barely notable, significantly worsening his already vulnerable recovery. Further exacerbating these nerfs, the universal changes hinder Diddy overall, as the more limited out of shield options and increased lag on grabs weaken his approach and defensive game with Banana Peel, while the faster knockback physics reduce his up throw's combo potential, no longer having reliable combos or KO setups at high percents. Lastly, Diddy's weight has been lowered, making him even easier to KO.

Diddy Kong did receive notable buffs, however. His neutral attack no longer has an infinite portion, which decreases its damage potential but allows it to connect much more reliably, improving its overall consistency and utility as a close range option. Some of his moves also have reduced lag that increases their combo ability, namely his dash attack, up tilt, down aerial, and down throw, the latter working better as an alternative to his up throw at lower percents. Game updates have further enhanced various aspects of Diddy's moveset: his up smash, down smash, and up aerial have increased KO power, his neutral aerial (previously his most situational aerial attack) is considerably more useful due to auto-canceling much earlier and having increased range, and Peanut Popgun deals more damage with a faster charge speed. However, these buffs do not fully compensate for the nerfs to more crucial aspects of Diddy's moveset.

Overall, Diddy Kong's nerfs outweigh his buffs, making him worse than his iteration in Smash 4. During Ultimate's early metagame, his overall perception has been negative, since notable Smash 4 Diddy Kong players such as MVD, Zinoto and Nietono have dropped him in favor of other characters, and he has suffered from minimal tournament representation. However, recent game updates (most notably version 3.1.0) have meaningfully buffed Diddy to a more substantial degree, and ZeRo has come back to maining him again; furthermore, Diddy has started to show signs of competitive success thanks to the efforts of Dakpo, who recently placed 13th at Low Tier City 7. As a result, Diddy Kong's viability in the competitive scene remains questionable.

The first hit transitions into the second hit faster (frame 9 → 6), which transitions into the third hit faster (frame 9 → 7). The third hit also has less startup lag (frame 9 → 5).

The first hit can be held for a consecutive jab.

The infinite portion has been removed; the third hit instead launches at a different angle (90°/85°/60° → 361°) and no longer deals set knockback (25/37 set/100 scaling → 60 base/80 scaling).

This makes the neutral attack much more consistent, no longer risking opponents escaping it before the final hit and punishing Diddy Kong. The third hit also has less ending lag compared to the previous neutral infinite's finisher (FAF 39 → 35).

However, the move deals much less damage overall as a result, despite all three hits having their damage values increased (1.2% → 2% (hit 1), 1.2% → 1.5% (hit 2), 2% → 4% (hit 3)). The third hit is also weaker compared to the previous neutral infinite's finisher, no longer KOing under 300% from the center of Final Destination.

Forward tilt has more base knockback (10 → 60), but less knockback scaling (100 → 60), and launches at a higher angle (361° → 45°). This increases it safety on hit at low percents, but more drastically reduces its KO potential, and removes its ability to lock.

Due to the changes to jostle mechanics, it can no longer whiff if initiated too close to an opponent.

The first and second hits have lower hitlag multipliers (1× → 0.5× (hit 1), 0.8× (hit 2)) and two additional hitboxes, with the second hit's also being larger (3.5u → 4u), allowing the move to connect more reliably.

The second and third hits have a longer hitbox duration (1 frame → 2 frames).

The first hit uses different angles (90°/60°/30° → 10°/45°/80°/22° (clean), 0° (late)) and set knockback values (28/35/42 → 20/35/25/42 (clean), 20 (late)), as well as weight-independent knockback, allowing it to connect more reliably into the second hit.

The second hit has one frame less startup (frame 22 → 21).

However, its total duration remains unchanged, giving it one frame more ending lag.

The first and second hits have received various changes to their angles and set knockback, and the second hit uses weight-independent knockback like the first, allowing the move to connect more reliably.

Its maximum charge time has been significantly reduced (90 frames → 60), to the point the fully charged version barely grants more distance than the uncharged version if used while falling, greatly hindering Diddy Kong's recovery.

Diddy Kong throws the Banana Peel in a higher arc, causing it to take longer to pick up afterwards.

The Banana Peel can hit opponents twice before disappearing rather than only once, bouncing off in a high arc on the first hit. This allows Diddy Kong to pick it up and throw it again, but shielding opponents can likewise punish Diddy Kong and steal the Banana Peel, leaving him more disadvantaged.

Diddy Kong has a new Final Smash, Hyper Rocketbarrel, which functions differently from Rocketbarrel Barrage. Diddy Kong flies through the stage in an erratic fashion to punch his trapped opponents. The final hit is where Diddy Kong does a delayed, aimed punch, dealing heavy knockback. Diddy Kong then lands and deactivates his Rocketbarrel Pack at the spot where he first used the move.

Diddy Kong claps in front of himself while crouching. An extremely versatile combo starter, as it can combo into a variety of moves at nearly any percentage, including down tilt to up smash as a notorious KO confirm.

Diddy Kong performs his signature Cartwheel attack from Donkey Kong Country, concluding with a double-handed ground-slap. The final hit has largely vertical knockback and can combo into aerials at low to mid percent ranges.

Diddy Kong jumps forward while spinning, and performs an open-handed slap followed by a spinning back fist with his opposite arm. The first hit combos into the second, which has good knockback and killing power. However, it is easily punished if missed. Often only used in combination with his banana peel.

Diddy Kong does an aerial cartwheel similar to his dash attack. Very high ending lag, so much so that Diddy Kong should avoid using this move offstage. However, it deals a low amount of vertical knockback, which can lead to potential footstools or aerial follow ups (though due to changes regarding footstooling, it is no longer an always-guaranteed option), giving it usage as a combo extender.

Diddy Kong performs an overhead kick in an arc. Tied for the fastest in the game (frame 4 startup) but the animation is faster with its duration unchanged, causing it to have a blindspot in front of Diddy.

Diddy Kong swings both arms downward in a double axe-handle punch. A strong meteor smash and Diddy Kong's strongest aerial overall, though it is also his slowest. It has a large auto-cancel window at the beginning of the attack before the hitbox starts, which makes it a good tool for landing provided that you input the move shortly before touching the ground. It can also jab lock opponents at low percent ranges.

Diddy Kong tosses his opponent forwards. The throw is based on Diddy Kong's barrel toss animation from Donkey Kong Country. Diddy Kong's second strongest throw, KOing middleweights around 156% at the edge of Final Destination.

Diddy Kong shoots a peanut from his Popgun. A safe projectile attack that is rather useful in neutral. It can also be canceled in the air if the shield button is held before inputting the special button, which is useful for B-reversing to make Diddy Kong's movement harder to predict. The peanuts have the property of items, and can be caught and thrown. The peanuts also bounce off of opponents and solid surfaces, but they lose their hitbox afterwards.

The longer Diddy Kong charges the attack, the farther and quicker the peanut will fly. If Diddy Kong overcharges the attack, however, it will cause a very powerful explosion that leaves him vulnerable but possesses massive knockback.

Diddy Kong performs a back-flipping forward leap that has him cling onto an opponent. Inputting the move as a smash attack increases the distance of the jump. Once he has clung onto the opponent, he will continuously scratch them. During this time, he can perform an action depending on what button is pressed: pressing the attack or special move button will cause Diddy Kong to attack them with a double-handed chop them and then leap away, while pressing the jump button will cause him to perform a pseudo footstool jump, which can meteor smash at high percentages. If the attack or special button is pressed during the jump, Diddy Kong will attack with a flying kick instead of latching on to his opponent. However, if Diddy Kong chooses to use the flying kick he will not be able to use his rocketbarrel pack unless he touches the ground first, making it a risky option offstage.

Diddy Kong charges his rocketbarrel pack from Donkey Kong 64 in a powerful attack. Can potentially fly very far and very fast when charged, however hitting a surface, or being hit, will make Diddy Kong lose his rocketbarrels before falling a huge distance while being unable to perform any action, often falling too far to survive. Diddy Kong will also take recoil damage for hitting a surface.

Diddy Kong tosses a Banana Peel over his shoulder and into the air to have it fall onto the ground. Grounded opponents who touch the peel while on the ground or are hit by the peel when thrown will slip and trip on the floor. An integral part of Diddy Kong’s kit, as it allows him to take control of the stage, extend and create combos, set up kills, easily punish missed attacks from his opponents even if they are spaced properly, and otherwise dominate the neutral game. A held banana also serves as one of the best out of shield options in the game when thrown. Only one banana peel can exist at one time, and it disappears when hit by an opponent or when thrown twice.

Diddy Kong activates his Rocketbarrel Pack and flies up. He then dashes across the screen in multiple directions, dealing damage to whoever he touches. After a while, he will lock on to whatever opponent has taken the most damage, and unleash one final dash attack that launches the targeted opponent, as well as any other nearby opponents. After this last attack, Diddy Kong descends back to his original position. His Rocketbarrel Pack explodes before he lands, which damages nearby opponents.

In Diddy Kong's path, he serves as the "little buddy" to the hero of various Nintendo franchises and fights the respective villains or final bosses. In the penultimate stage he finally teams up with his true partner, Donkey Kong, to defeat their nemesis King K. Rool. Donkey Kong is also Diddy Kong's partner for the final fight against Master Hand and Crazy Hand. The title originated from the manual of Donkey Kong Country and was popularized by the Donkey Kong Country TV series; Diddy Kong is also referred to as Donkey Kong's "little buddy" in games such as Brawl and Donkey Kong Country Returns.

Diddy Kong was among the fighters that were summoned to fight the army of Master Hands.

Diddy Kong was present on the cliffside when Galeem unleashed its beams of light. He attempted to fly away with Rosalina & Luma using his activated Rocketbarrel Pack, but a beam of light hit him and he was vaporized and placed under Galeem's imprisonment along with the other fighters, excluding Kirby.

To find Diddy Kong, the player must access the Kongo Jungle sub-area reminiscent of the first Donkey Kong Country game, where he's found right at the end.

Diddy Kong's Fighter Spirit can be obtained by completing Classic Mode. It is also available periodically for purchase in the shop for 500 coins. Unlocking Diddy Kong in World of Light allows the player to preview the spirit below in the Spirit List under the name "???". As a Fighter Spirit, it cannot be used in Spirit Battles and is purely aesthetic. Each Fighter Spirit has an alternate version that replaces them with their artwork in Ultimate.
